Consideration before buying OAP - WeirdMan - 05-04-2021
Hi, I am planning to build pi head unit and considering OAP. I have few questions since I cannot find it in the forum.
1. Is it possible to use Android auto without touch interface? I have non touch screen to be used.
2. Can wifi become client? I want it to be connected to my house wifi to do data sync, updating, etc. Automatically when I arrive home.
3. I cannot find videos on OAP running its features except for playing music, showing OBD II results on dash. Is there any?
4. Is there any person who succeed using USB Webcam as dash cam in OAP? Is there any installation guide for that? Also, AFAIK USB cannot use cable more than 5m.
5. Can gesture control used to navigate OAP replacing keyboard?
6. Is there anyone succeeded using other touch screen than original pi touch screen? Many seller in my country advertised knockoff product as original and I afraid it will not be compatible.
Thanks for answering.

Here are some answers:
1. Yes, see videos on YT
2. Depends if you would like to use wireless AA or not. Additional WiFi card maybe be required. Matter of your knowledge about Wifi configuration in Raspberry Pi OS
3. Here is our channel: https://www.youtube.com/channel/UC2FLUTV7s3Bf9hld7eQdrog
4. There are users that have USB cameras installed. Search in YT and check projects: https://bluewavestudio.io/community/forumdisplay.php?fid=62
5. No, list of gestures is limited. Check on our YT channel
6. Matter of configuration under RPI. Check users projects.
Hope this helps.

I am using a Sunfounder 10.1 touch display and it works perfectly. The only difference is that is uses the HDMI (display) and USB (touch) instead of the flat ribbon cable.

I am using a 7" 1024x600 with capacitive touch from a company called Buydisplay on Ebay. They also have a website you can order from, but I found it easier to order through Ebay. When you order both the display and touchscreen at the same time they will bond the touchscreen to the display for you for free. They have several driver boards. I got the one with the HDMI, VGA, Video Driver board. It's the larger of the driver boards and I use HDMI. This board also allows me to have native reverse cam. There is a JST plug on the board that when you supply 12V to it, it changes to the RCA video input. I don't process reverse video cam on the Pi, it does not even have to be booted up. Putting my car in reverse powers up the screen and triggers the reverse input on the driver board. If the Pi is booted, and I put it in reverse, the screen changes to the reverse cam, and the Pi knows nothing about it. After leaving reverse, it switches back to the normal display, or turns the screen off if the Pi was not already turned on.
I also ordered a screen from them for another project, and they were pretty easy to work with. With that project I ordered the smaller driver board that had no Video input. I wanted the reverse cam, so they allowed me to purchase the larger driver board separately. They also have options for extender cables for power and VGA for about USD $0.50 each, well worth it.
Prices on the displays are currently about USD $20 higher than what I paid back in the beginning of 2020 though.
